Thanks for your comments. I launched my main site, which focuses on cruises, about a year ago. I loaded it with good, original content and I add content frequently. All pages are SEO'd but the field is very crowded. I joined CJ and Linkshare, launched a PPC effort with AdWords, but the ROI wasn't there. Affiliate text/banners are now replaced by AdSense. I'm doing this full time as I'm another engineering-type who's job now no longer exists in the US.
